Solution

1. Preparation

Gather tools: socket set, multimeter, wire brush, safety gloves, and safety glasses.
Disconnect the battery (negative terminal first) to ensure safety during repairs.

2. Battery Inspection and Cleaning

Check Battery Terminals
- Inspect the battery terminals for corrosion.
- Clean terminals using a wire brush if corrosion is found.
Tighten Connections
- Ensure the terminals are securely tightened to avoid poor electrical contact.

3. Battery Replacement (if necessary)

Remove Old Battery
- Loosen and remove the battery hold-down clamp with the appropriate socket.
- Carefully lift the battery out of the tray, ensuring not to tip it.
Install New Battery
- Place the new battery into the tray, ensuring the terminals are positioned correctly (positive to positive, negative to negative).
- Secure the battery with the hold-down clamp and tighten it.
Reconnect Battery
- Connect the positive terminal first, followed by the negative terminal.

4. Starter Relay and Motor Inspection

Check Starter Relay
- Locate the starter relay in the fuse box.
- Swap the starter relay with a similar relay to test functionality.
Test Starter Motor
- If the clicking persists, check the starter motor connections.
- If accessible, tap the starter lightly with a hammer while a helper attempts to start the engine to see if it engages.

5. Final Connection Check

Double-check all connections, ensuring no wires are frayed or damaged.
Reconnect the battery terminals if they were disconnected during the process.
